  • Aerial Radiation Detection

    In this time of multiple threats to our security: dirty bomb; cyber; shooters in public places; homemade bombs; misinformation; etc. we feel extremely vulnerable; perhaps more vulnerable than ever before. With the advent of Drone technology now available to private citizens, technology previously only held by the military, the opportunity has come to marry Drone Technology with aerial sensors. ...

  • Ionising Radiation

    Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

  • Development of an in vivo assay for detection of non-targeted radiation effects

    An adaptive response may be defined as the effect of a small priming dose of radiation modifying the anticipated cellular response of the same tissues so as to alter the predicted response to a larger dose of radiation. We and many others have demonstrated that at low radiation doses (less than 0.5 Gy) the lethal and mutational effect of the radiation is mainly, possibly entirely, due to the ...

  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

  • Individual radiosensitivity: a key issue in radiation protection

    Immunofluorescence that permits the detection of nuclear targets specific to DNA damage signalling and repair have completely renewed the approach of individual radiosensitivity. It is a concern in radiotherapy in which radiosensitivity is responsible for the development of adverse side–effects in normal tissues in absence of any mistake in the dose delivery. Furthermore, individual ...

  • The lack of acute effect of low–to–moderate–dose ionising radiation on endothelial proteome

    Epidemiological studies have shown that moderate and low radiation doses to the heart area may result in an increase in cardiovascular mortality. It has been suggested that cardiovascular endothelium could be one of the targets for the ionising radiation–induced heart injury. We have used human endothelial cells as an in vitro model to study immediate effects of ionising radiation on endothelium. ...

  • Radiation Water Monitor in Real-Time and Continuous at Jefferson NL 2006

    Jefferson National Laboratory is a high tech laboratory located on a beautiful campus in suburban Virginia. Their research is centered on their high-energy electron accelerator. Energies generated are as high as 6 Gev continuous with currents up to 200 micro Amps. Where does the high-energy accelerator beam go after smashing atoms in the experimental sample? It impacts into a tank of purified ...

  • Chromosomal aberrations in Iranian radiation workers due to chronic exposure of X-irradiation

    The frequency of chromosomal aberrations in the peripheral blood lymphocytes of 65 radiology technologists working in hospitals in Tehran, Iran, who had been chronically exposed to X-rays, was analysed. Although film dosimetery did not show the maximal annual permitted dose (20 mSv per year) in any of the examined subjects, cytogenetic analysis detected fairly high levels of chromosomal ...

  • Why is there no effective real-time Continuous Radiation Monitoring System?

    Japan's disaster has raised many questions regarding safety of the public. It has served as a wakeup call to the agencies tasked with protecting the public. Not least of these questions, but certainly the most far-reaching is the question of the safety of nuclear power and radiation contamination of air and water. Way back when nuclear power was first established, in the 1960s public opinion was ...

  • Value addition in diamonds and other gemstones by nuclear radiation: the phobias and safety considerations

    Four Cs, namely colour, clarity, carat (weight) and cut, primarily determine the price of a gem. Neutron irradiation, gamma rays and electron beams can be used to enhance the colour and clarity of aquamarine, quartz, tourmaline, kunzite, topaz, pearls and, most importantly, diamonds. Imparting colour and clarity to these gems that are otherwise devoid of these attributes results in significant ...

  • Chromosomal aberrations in radiation workers of radiology departments in Northern Iran-Babol

    We determined the frequency of chromosomal aberrations using the metaphase analysis method in radiation workers of radiology departments in Babol. Blood samples were prepared from 62 radiology workers and 29 individuals as controls, and lymphocytes were cultured in a culture medium. Results showed that the mean frequencies of the total chromosomal aberration in radiation workers are significantly ...

  • A database of cancer induction by low-dose radiation in mammals: overview and initial observations

    The lifespan studies of animals exposed to low doses of ionizing radiation with a view to determining the relationships between radiation dose and cancer incidence have been identified and corresponding publications have been reviewed. The information on experimental conditions and cancer incidence data in exposed and control animals have been entered into a database intended for a global ...

  • Immune cells in Chernobyl radiation workers exposed to low dose irradiation

    Immune response parameters were studied in Chernobyl radiation emergency workers exposed to low-dose irradiation during 1986–1989 and nuclear industry workers exposed under professional limits. Analysis was performed in irradiation dose limits of 250 and 100 mSv. The comparison group included participants of the clinical–epidemiological registry (n – 42,000) studied in the same time periods. The ...

  • Gas Detection in Public Swimming Pool Facilities

    Recreational facilities’ indoor swimming pools provide a venue for exercise, competition and fun for all ages as patrons splash, swim, dive and float around in the crystal clear water. To keep the water fit to swim in requires a disinfectant maintenance program commonly using Chlorine, or Chlorine and Ozone. Chlorine is a powerful, corrosive disinfectant and in both gas and liquid forms it ...

  • Detecting Hydrogen Gas and Fires: Seeing the Unseen

    Hydrogen usage is growing. The general public sees and reads about hydrogen as an alternative fuel for cars. However, the big use for hydrogen is found in hydrocarbon processing and other important manufacturing processes. Hydrogen is the first element on the periodic table and is an essential element in the manufacturing of many of our everyday products. We must have respect for its explosive ...

  • Detection and measurement of GWGs in semiconductor fab facilities

    Problem Statement Various processes and tools in the modern wafer fab plant produce effluent streams that contain unacceptably high levels of perfluorocarbon GWGs (greenhouse warming gases). These effluent streams are abated by plasma incineration and wet scrubbers and other techniques. It is necessary to measure the destruction removal efficiency (DRE) of the various abatement methods ...

  • Ionising radiation or chemical utagen induced chromosome aberration in lymphocytes from epidemiological data at Vietnam

    Studies on epidemiology of chromosome aberration induced in human lymphocytes were conducted in 81 donors selected from five agricultural inhabitant populations. The abnormal frequencies of chromosome aberrations were detected in four of the five investigative groups that had not been controlled for any environmental toxic contamination before. The completed and complicated band of detected ...

  • GOOD NEWS FOR DRINKING WATER Independent Test Lab Evaluates Instrumentation forDetecting Radiation in Drinking Water

    Since 9/11 and there are still holes in security of the nation’s infrastructure, particularly for drinking water. This security deficit is currently being addressed in some community water systems with water monitoring instruments. In the 90s the EPA developed a wish list for monitoring contaminants in drinking water. Since that time biological and chemical contaminants have been identified ...
